I HAVE AN ONGOING PROBLEM WITH THE BRAKES ON MY 1990 BUICK REGAL. AFTER MANY REPAIRS AND REPLACEMENTS TO THE FRONT BRAKE SYSTEM . I DISCOVERED THAT THE ROOT CAUSE WAS THE MALFUNCTION OF THE REAR BRAKES. THE REAR CALIPERS ARE DESIGNED, THAT WHEN THEY CORRODE THE BRAKING ACTION IS DIMINISHED AND EVENTUALLY STOPS WHEN THE CALIPERS ARE COMPLETELY FROZEN. THIS FAILURE CAUSES SUBSEQUENT PROBLEMS : 1. BECAUSE THE FRONT BRAKES NOW CARRY MORE BREAKING LOAD THE PAD WEARS OUT VERY QUICKLY. 2. BECAUSE THE FRONT BRAKES NOW CARRY MORE BREAKING LOAD THE ROTORS WILL WARP AND REQUIRE FREQUENT TURNING, WHICH EVENTUALLY RENDERS THE ROTOR BELOW SPECIFIED THICKNESS AND MUST BE REPLACED . 3. THE REAR CALIPERS CAN SOMETIMES LOCK IN THE ENGAGED POSITION. THIS WILL CAUSE EXCESS AND POTENTIALLY DANGEROUS HEAT IN THE BRAKES. THIS WILL EVENTUALLY RUIN ROTORS AND MAY PRESENT A FIRE HAZARD. 4. THE LACK OF BREAKING IN THE REAR OF THE VEHICLE CAUSES AN IMBALANCE IN THE BREAKING CHARACTERISTICS OF THE VEHICLE. THIS WILL CAUSE THE VEHICLE TO LERCH SIDEWAYS IN AN EMERGENCY BREAKING SITUATION AS THE INERTIA FROM THE REAR IS NOT IMPEDED, MAKING IT IMPOSSIBLE TO STOP WITH ANY CONTROL. I HAVE EXPERIENCED ALL 4 OF THESE CONDITIONS ON MY VEHICLE. ITEMS 1-3 ARE TROUBLESOME BECAUSE THE COST IMPACT HAS BEEN SIGNIFICANT . BUT THE 4TH ITEM IS CAUSE FOR MY GREATEST CONCERN AS I SEE THIS AS A SERIOUS LIFE AND SAFETY DEFECT. I HAVE EXPERIENCED FIRST HAND THE EFFECT OF THIS CONDITION WHEN MAKING AN EMERGENCY BREAKING MANEUVER. MY VEHICLE LITERALLY SNAPPED SIDEWAYS INTO THE ONCOMING LANE WHEN I HAD TO JAMB ON THE BREAKS. LUCKILY BECAUSE THE ROAD CONDITIONS WERE DRY AND TRAFFIC WAS LIGHT, I WAS ABLE TO GAIN CONTROL AND EVENTUALLY STOP THE VEHICLE. AN ADDITIONAL IMPORTANT FACTOR IS, THERE IS NO ADVANCED INDICATION THAT THE REAR CALIPERS HAVE FROZEN OR NOT FUNCTIONING PROPERLY, PUTTING THE SAFETY OF OPERATOR AND PASSENGERS AT SIGNIFICANT RISK. THIS MUST EFFECT ALL THE OTHER GM MODELS THAT HAVE THE

VEHICLE HAS BEEN EXPERIENCING EXTENDED STOPPING DISTANCES/FADING. THE VEHICLE HAS BEEN IN TWO COLLISIONS DUE TO THE BRAKES NOT ENGAGING AND GIVING SUFFICIENT BRAKING DISTANCE.
